A racquet including a frame including a head portion, a handle portion, and a throat portion. The head portion is a tubular structure including inner and outer peripheral walls, each having inner and outer surfaces. The head portion of the racquet being formed of a fiber composite material. The fiber composite material includes a plurality of ply arrangements. Each includes a pair of plies defining first and second angles with respect to a composite axis. A section of the outer peripheral wall from the inner surface to the outer surface includes at least three ply arrangements overlaying each other, and the first and second angles of at least two of the at least three ply arrangements being at least 35 degrees. When the racquet is tested under a racquet torsional stability test, the racquet has an angular deflection of less than 5.5 degrees about a longitudinal axis.

A construct for a hockey stick formed from layers of fiber tape and a reinforcing nanofiber material. The nanofiber is integrated into the molded hockey stick to increase the strength and toughness of inter-laminar bonds between the fiber tape. The nanofiber may include carbon nanotubes.

A light-weight composite material with enhanced structural characteristics includes, in one embodiment, a compositionally modulated nanolaminate coating electrically deposited into an open, accessible void structure of a porous substrate. As a result of including a nanolaminate within the void structure, the composite can include a greater amount of nanolaminate material per unit volume than can be achieved by depositing a nanolaminate material solely on a two-dimensional surface. In addition, the nanolaminate material as well as other material electrodeposited to form the composite is compositionally modulated so that discontinuities between layers are minimized and potentially eliminated. The light-weight but structurally enhanced composite material can be used in a number of different applications including, but not limited to, ballistic applications (e.g., armor panels or tank panels), automotive protection applications (e.g., car door panels, racing shells) and sporting equipment applications (e.g., golf club shafts and tennis racket frames).

A racquet extends along a longitudinal axis and is capable of being tested under a racquet lateral bending test and a racquet torsional stability test. The racquet lateral bending test includes mounting the racquet in a first orientation to a first test fixture at a first longitudinal location, attaching a clamp to the racquet at a second location, operably engaging a deflection indicator to the clamp, applying a first predetermined weight to the racquet at a third location, and removing the first weight to obtain a lateral deflection measurement of the racquet with respect to the longitudinal axis. The racquet torsional stability test includes mounting the racquet to second and third test fixtures at sixth and seventh locations of the racquet, respectively, placing a third predetermined weight on an arm extending from the second test fixture, removing the third predetermined weight to obtain an angular deflection about the axis. The racquet comprises a frame including head and handle portions and a throat portion positioned between the head and handle portions. The head portion forms a hoop that defines a string bed plane. When the racquet is tested under the racquet lateral bending test, the racquet has a lateral deflection of at least 6.0 mm when measured in a direction that is parallel to the plane and perpendicular to the axis. When the racquet is tested under the racquet torsional stability test, the racquet has an angular deflection of less than 5.0 degrees about the axis.
